8.1 litres = approx 490 cu "
How would you go if you wanted to upgrade your coil(s) in one of those things? That's gotta inflict some nasty pain in the wallet region for sure.;eek

Any info on what block he used? I am presuming the motor came from something older than the car it went into or it came from a truck.

C5 and even C5R blocks can't be taken out that far to my knowledge.

Diagnosing an ignition problem could be more fun than normal too. ;eek Not that I'd turn down a C5 if one was offered to me. :)

VO,

Apparently, the 8.1L translates to a 496CID engine. Its the truck engine that is
used in the 3/4T truck lines.

She puts out 340Hp and 475FT/Lbs of torque which I thought was a little low actually. There's also a marine verson that's rated at 375hp.

I dare say that this would very well be the ONLY huge block C5 around.

ps: 7cvt-> r those red x's attempts to post smilies ... ?

Things have changed a little now. I pasted the address of 77CVT's link into a new window and got the pic.

BTW, when I couldn't get it yesterday I checked the links properties and had a pretty good idea of what it would have been. Turns out I was right. :22

Thanks for the info.

Assuming all that info is spot on and the car in question is a Z06, the car has dropped a minimum of 45hp but picked up about 90 FT/LB of torque (based on a 2001 (first year) Z06).

I admire and respect the work and ingenuity with the swap but if it were my car I would have played with some bolt ons or done the heads and cam. Then again, it's not my car. Just my opinion.

Definitely wins bragging rights though, I bet he's got the biggest cubed C5 on his block. ;35

VO.....GREG morris from corvette conversion has done the sums, the measurements and knows the right 500cube motor and harness that will fit in a C4............now that'd be a REAL GUTTER SLAPPER LOL :);)

VO, the authenticity is looking a little dubious now as why would anyone want to drop 45 horses ? Perhaps it wasn't a Z06. Whilst on the subject of dropping power like this, I noticed in the current Unique Cars a Victorian vette for sale that reads "used to be a big block now a 350cid" .... I'm not being critical but why would anyone want to change a big block 4 speed to a small block 4 speed ?
